Iposwe kwi 2018-09-10Ifilimu yeDacromet iqulethe i-zinc ecocekileyo yentsimbi, i-aluminium powder kunye nechromate.Yintsimbi yentsimbi engwevu ye matt efunyenwe emva kokwaleka kunye nokubhaka.Ikwabizwa ngokuba yi-zinc flake coating.Nangona i-Dacromet i-coating ijongeka kakhulu njengomaleko owenziwe nge-electrogalvanized, i-Dacromet yokwambathisa ineengenelo ezinokuthi iileya zemveli ezifakwe zinc azikwazi ukuhambelana:
1) Akukho brittle ye-hydrogen.Inkqubo yeDacromet ayinayo i-asidi kwaye ayinayo ingxaki ye-hydrogen permeation.Kufanelekile ngokukhethekileyo kwiibholiti eziphezulu zamandla kunye neengxenye ze-elastic emva kokunyanga kwiqondo lokushisa eliphezulu.
2) Inkqubo ayinangcoliseko.Inkqubo yonyango ye-Dacromet ngokusisiseko ayinayo inkunkuma emithathu, ngoko ibangela ukuba akukho ngcoliseko yendalo esingqongileyo.
3) Ukumelana kakhulu nokubola.Ifilimu ye-Dacromet incinci kakhulu, kodwa umphumo wayo wokukhusela kwiindawo zetsimbi ngama-7-10 amaxesha e-electroplated zinc layer yobukhulu obufanayo.Ingubo ye-Dacromet efunyenwe ngokutya okuthathu kunye nokubhaka okuthathu kunokumelana nokutshiza kwetyuwa engathathi hlangothi ngaphezu kwe-1000h.
4) Ukugqithiswa okuphezulu kunye nokuchasana nobushushu obugqwesileyo.Inkqubo yonyango ye-Dacromet ifakwe okanye igqunywe, kwaye akukho ngxaki yokuchithwa kakubi kunye nobuchule obunzulu bokubethelwa ngenxa yesakhiwo esinzima se-workpiece, kwaye i-coating ingasetyenziselwa ngokuqhubekayo ixesha elide kwindawo ye-250 degree, kunye ne-corrosion. ukuchasana kugcinwa, imbonakalo ayichaphazeleki.
I-5) Ukuxhatshazwa kwe-electrochemical corrosion kwi-zinc-aluminium bimetal.Uninzi lwezinki zisebenza kakuhle kunye ne-aluminium okanye i-substrates yensimbi ukuvelisa ii-microbattery ze-bimetallic eziqhelekileyo, kunye ne-aluminium flakes kwi-coating ye-Dacromet iphelisa le nto.
6) Ubuchule bokuphinda bomelele kakhulu.Ingubo ye-Dacromet inokuphinda ikwazi ukuphinda ikwazi ukuphinda iphinde ifakwe kwipeyinti yesibini kumphezulu we-workpiece emva kokucubungula.
